A nurse in a prenatal clinic is caring for a client who wants to know her estimated date of delivery if her last menstrual period was on May 4, 2022.
What should the nurse respond?
April 11, 2023.
February 11, 2023.
February 27, 2023.
April 27, 2023.
The Correct Answer is B
We use Nägele’s Rule to estimate the date of delivery:
? Formula:
First day of LMP + 7 days − 3 months + 1 year
-
LMP = May 4, 2022
-
Add 7 days → May 11, 2022
-
Subtract 3 months → February 11, 2022
-
Add 1 year → February 11, 2023
✅ Estimated Date of Delivery (EDD): February 11, 2023

Correct Answer is ["B","C","D"]
Explanation
Choice A rationale
Cephalopelvic disproportion refers to a mismatch between the size of the fetal head and the mother’s pelvis, making it difficult for the baby to pass through the birth canal. This condition is not identified through amniocentesis.
Choice B rationale
Amniocentesis is a procedure where a small amount of amniotic fluid, which contains fetal tissues, is sampled and tested. This test can indeed identify anomalies in fetal chromosomes. It can detect genetic disorders such as Down syndrome, spina bifida, and cystic fibrosis.
Choice C rationale
Neural tube defects, such as spina bifida, can be detected through amniocentesis. These defects occur when the neural tube, which forms the brain and spinal cord, fails to close completely during the first few weeks of embryonic development.
Choice D rationale
Amniocentesis can also determine the fetal gender. This is because the test analyzes the chromosomes present in the fetal cells found in the amniotic fluid. Males have XY chromosomes, while females have XX chromosomes.
Choice E rationale
Rh incompatibility is a condition where the mother’s Rh blood type and the baby’s Rh blood type are incompatible. This can lead to the mother’s immune system attacking the Rh positive cells of the baby. However, Rh incompatibility is not detected through amniocentesis. It is typically identified through blood tests.
Correct Answer is C
Explanation
Choice A rationale
While iron is an important nutrient during pregnancy, it does not specifically help prevent neural tube defects in the fetus.
Choice B rationale
Vitamin C is an essential nutrient for overall health, but it is not specifically linked to the prevention of neural tube defects.
Choice C rationale
Folic acid is the supplement recommended to help prevent neural tube defects in the fetus. It is crucial for the proper closure of the neural tube during early fetal development.
Choice D rationale
Calcium is important for the development of the baby’s bones and teeth, but it does not specifically help prevent neural tube defects.
